Chapter 1  
Product introduction  
Thank you for buying an ASUS® AT5NM10-I motherboard!  
Before you start installing the motherboard, and hardware devices on it, check the items in  
your motherboard package. Refer to page ix for the list of accessories.  
If any of the items is damaged or missing, contact your retailer.  
1.1  
Before you proceed  
Take note of the following precautions before you install motherboard components or change  
any motherboard settings.  
Unplug the power cord from the wall socket before touching any component.  
Before handling components, use a grounded wrist strap or touch a safely grounded  
object or a metal object, such as the power supply case, to avoid damaging them due to  
static electricity.  
Hold components by the edges to avoid touching the ICs on them.  
Whenever you uninstall any component, place it on a grounded antistatic pad or in the  
bag that came with the component.  
Before you install or remove any component, ensure that the ATX power supply is  
switched off or the power cord is detached from the power supply. Failure to do so may  
cause severe damage to the motherboard, peripherals, or components.  
Onboard LED  
The motherboard comes with a standby power LED that lights up to indicate that the system  
is ON, in sleep mode, or in soft-off mode. This is a reminder that you must shut down  
the system and unplug the power cable before removing or plugging in any motherboard  
component. The illustration below shows the location of the onboard LED.

1.4.2  
Memory configurations  
You may install 512MB, 1GB, and 2GB unbuffered non-ECC DDR2 DIMMs into the DIMM  
sockets.  
Always install DIMMs with the same CAS latency. For optimum compatibility, it is  
recommended that you obtain memory modules from the same vendor.  
Due to the memory address limitation on 32-bit Windows® OS, when you install 4GB  
or more memory on the motherboard, the actual usable memory for the OS can be  
about 3GB or less. For effective use of memory, we recommend that you do any of the  
following:  
-
-
Use a maximum of 3GB system memory if you are using a 32-bit Windows® OS.  
Install a 64-bit Windows® OS when you want to install 4GB memory on the  
motherboard.  
When you install 4GB memory on the motherboard, the memory that the system can  
detect is less than 4GB.  
This motherboard does not support DIMMs made up of 256 megabits (Mb) chips or less.

Expansion slot  
In the future, you may need to install expansion cards. The following sub-sections describe  
the slot and the expansion cards that it supports.  
Unplug the power cord before adding or removing expansion cards. Failure to do so may  
cause you physical injury and damage motherboard components.  
1.5.1  
Installing an expansion card  
To install an expansion card:  
1.  
Before installing the expansion card, read the documentation that came with it and  
make the necessary hardware settings for the card.  
2.  
3.  
Remove the system unit cover (if your motherboard is already installed in a chassis).  
Remove the bracket opposite the slot that you intend to use. Keep the screw for later  
use.  
4.  
Align the card connector with the slot and press firmly until the card is completely  
seated on the slot.  
5.  
6.  
Secure the card to the chassis with the screw you removed earlier.  
Replace the system cover.  
1.5.2  
Configuring an expansion card  
After installing the expansion card, configure it by adjusting the software settings.  
1.  
Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for  
information on BIOS setup.  
2.  
3.  
Assign an IRQ to the card.  
Install the software drivers for the expansion card.  
1.5.3  
PCI slot  
The PCI slot supports cards such as a LAN card, SCSI card, USB card, and other cards that  
comply with PCI specifications.

Jumpers  
1.  
Clear RTC RAM (3-pin CLRTC)  
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can  
clear the CMOS memory of date, time, and system setup parameters by erasing  
the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in  
CMOS, which include system setup information such as system passwords.  
To erase the RTC RAM:  
1. Turn OFF the computer and unplug the power cord.  
2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3  
for about 5-10 seconds, then move the cap back to pins 1-2.  
3. Plug the power cord and turn ON the computer.  
4. Hold down the <Del> key during the boot process and enter BIOS setup to re-enter  
data.  
Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default  
position. Removing the cap will cause system boot failure!  
If the steps above do not help, remove the onboard battery and move the jumper again to  
clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery.

Keyboard/mouse power (3-pin PS2_USBPW1-4)  
This jumper allows you to enable or disable the keyboard/mouse and USB port 1-4 wake-up  
feature. When you set this jumper to pins 2-3 (+5VSB), you can wake up the computer by  
pressing a key on the keyboard (the default is the Space Bar), clicking the mouse or using  
a USB device. This feature requires an ATX power supply that can supply at least 1A on the  
+5VSB lead, and a corresponding setting in the BIOS. The USBPW1-4 jumper is for the rear  
USB ports.

(Default)  
AT5NM10-I Keyboard Power Setting  
The total current consumed must NOT exceed the power supply capability (+5VSB) whether under  
normal condition or in sleep mode.  
3.  
USB device wake-up (3-pin USBPW5-8)  
Set this jumper to +5V to wake up the computer from S1 sleep mode (CPU stopped, DRAM  
refreshed, system running in low power mode) using the connected USB devices. Set to  
+5VSB to wake up from S3 and S4 sleep modes (no power to CPU, DRAM in slow refresh,  
power supply in reduced power mode).  
The USB device wake-up feature requires a power supply that can provide 500mA on the  
+5VSB lead for each USB port; otherwise, the system would not power up.  
The total current consumed must NOT exceed the power supply capability (+5VSB) whether  
under normal condition or in sleep mode.

Internal connectors  
1.  
ATX power connectors (24-pin EATXPWR, 4-pin ATX12V)  
These connectors are for ATX power supply plugs. The power supply plugs are  
designed to fit these connectors in only one orientation. Find the proper orientation and  
push down firmly until the connectors completely fit.  
We recommend that you use an ATX 12V Specification 2.0-compliant power supply unit  
(PSU) with a 450W or lower power rating. This PSU type has 24-pin and 4-pin power  
plugs.  
If you intend to use a PSU with 20-pin and 4-pin power plugs, ensure that the 20-pin  
power plug can provide at least 15 A on +12 V and that the PSU has a power rating of  
450W or lower. The system may become unstable or may not boot up if the power is  
inadequate.  
DO NOT forget to connect the 4-pin ATX +12V power plug. Otherwise, the system will  
not boot up.  
If you are uncertain about the minimum power supply requirement for your system,  
com/PowerSupplyCalculator/PSCalculator.aspx?SLanguage=en-us for details.
